I keep getting “The underlying connection closed” messages – odd. Also my modification to the previous entry didn’t look quite right, because (I guess) when you edit an entry ecto forgets my default formatting mode (convert line breaks).
Overall I think this will definitely be easier than hacking raw HTML, as I do now. The other candidate is the full version of NetNewsWire, but I may have complicated life for myself by testing their latest beta, in which the editor is apparently broken. And of course NetNewsWire is Mac only, which is OK in principle and awkward in practice.
